Customer Review: Not bad, worth the money for a simple wide angle
Basically this works by screwing onto the end of your lens like a filter. There is a conversion ring for the Cannon lens, a 58 series VII (46mm to 58mm) adapter. It does open up the wide angle aspect of the lens, but it also cuts down on the light you are getting. I think with the faster 50mm lens it gives you a really nice wide angle lens that isn't as dark. As for the Macro aspects, not really any better than the stock lens. Also a pure wide angle or fisheye is probably better, but the price on this was right for what I wanted. Haven't shot much with it yet, but so far it looks okay.
